Exactly. 2 big questions marks for me:
1)upgrading the exhaust headers and piping but retaining the stock cats and muffler = probably net gain of zero 
2)upgrading plenum, intake but retaining smaller MAF = probably net gain of zero.
The car should not need a piggyback signal massage device like the Apexi if it were setup correctly.
